Preparation method of silicon nitride full-ceramic ball valve
The invention discloses a preparation method of a silicon nitride full-ceramic ball valve. According to the preparation method of the silicon nitride all-ceramic ball valve, the silicon nitride all-ceramic ball valve is prepared through a forming processing sintering technology, and the silicon nitride all-ceramic ball valve comprises a ball core and two valve seats; rough machining is conducted on the ball core and the two valve seats, and the allowance on the surfaces of the ball core and the two valve seats is removed; a grinding strip is adopted, grinding materials are added on the way, finish machining is conducted on the ball core and the two valve seats, the soft sealing use requirement is met, the ball core and the two valve seats are assembled, and the ball core and the two valve seats are tightly matched to achieve sealing. The problems that in the preparation process of an existing silicon nitride full-ceramic ball valve, after the silicon nitride full-ceramic ball valve is formed, machined and sintered, sealing among a ball core and two valve seats cannot be guaranteed, and the use requirement for sealing of the ball valve cannot be met are solved.
本发明公开了一种氮化硅全陶瓷球阀的制备方法。本发明的氮化硅全陶瓷球阀的制备方法，通过成型加工烧结工艺制备氮化硅全陶瓷球阀，所述氮化硅全陶瓷球阀包括球芯和两个阀座；对所述球芯和两个阀座进行粗加工，去除所述球芯和两个阀座表面的余量；采用砂条并在途中加上磨料，对所述球芯和两个阀座进行精加工，达到软密封使用要求，将所述球芯和两个阀座进行装配,将所述球芯和两个阀座紧密配合达到密封；解决了现有的氮化硅全陶瓷球阀的制备过程中，氮化硅全陶瓷球阀通过成型加工烧结后，无法保证球芯和两个阀座这三者之间的密封，无法达到球阀密封的使用要求的问题。
